Dysprosium

The Heat Shield of the Magnet World

Dysprosium takes its name from the Greek dysprositos, meaning “hard to get.” While it may be difficult to isolate, it is impossible to ignore in the era of high-performance technology. Dysprosium is the critical “force multiplier” that allows super-magnets to operate in extreme heat. Without it, the high-performance traction motors in electric vehicles and the massive generators in offshore wind turbines would fail under operational stress.As a leading UK manufacturer, Less Common Metals (LCM) bridges the gap between raw potential and industrial application. Based in Ellesmere Port, we provide the high-grade Dysprosium metal (classified as a “Critical” Heavy Rare Earth) essential for global energy independence and advanced nuclear safety.

Dysprosium Capabilities & Technical Grades

At LCM, we offer both standard and ultra-high purity grades to meet the exacting requirements of the magnetics and nuclear sectors:

  • High-Coercivity Magnet Grades: Specialised additives for Neodymium (NdFeB) magnets that dramatically increase their resistance to demagnetisation (coercivity) at high temperatures.
  • Nuclear Control Grades: High-purity Dysprosium utilised for its high thermal neutron absorption cross-section, ideal for regulating nuclear reactors.
  • Magnetostrictive Grades (Terfenol-D): A core component in shape-shifting alloys that expand and contract in magnetic fields for use in precision sonar and sensors.

Data Storage & Recording Grades: Alloys designed for high magnetic susceptibility in high-density recording media and hard disk drives.
